MultiBoot MultiBoot Results Before changing the startup sequence, consider the following: ■ When the notebook restarts after the boot order has been changed, it considers only the first of each type of device (except for optical devices). For example, suppose that the notebook is connected to an optional docking device (select models only) that contains a hard drive. This hard drive is shown in the boot order in Computer Setup as "USB hard disk." If this drive is placed before the hard drive in the primary hard drive bay in the boot order, and if the system fails to boot to the drive in the docking station, it will not attempt to boot to the hard drive in the primary hard drive bay. Instead, it will try to boot to the next type of device in the boot order (diskette, optical device, or NIC). However if there are two optical devices and the first optical device does not boot (either because it does not contain media or the media is not bootable), the system will try to boot to the second optical device. ■ Changing the boot sequence also changes the logical drive designations. For example, if you start up from a CD-ROM drive with a disc that boots as drive C, that CD-ROM drive becomes drive C and the hard drive in the hard drive bay becomes drive D. ■ Starting up from a NIC does not affect logical drive designations because no drive letter is associated with the NIC. ■ Drives in an optional docking device are treated like external USB devices in the boot sequence and must be enabled in Computer Setup.
